Your car has no rear sway bar so a control arm bushing/shock issues will be amplified. Even a small factory bar would help tie stuff together.

Push up/down on the rear fender and see if the car continues to move after you shop pushing. If so, you need shocks.

You would know pretty quick if the lug nuts were loose enough for the car to feel loose, as the studs will break after a couple miles.

sorry but I don't understand what you advise to try to see if I need shocks ? what is the rear fender ? I must see if the car continues to move after I shop pushing ? what does this mean ?


It's strange that I have not a rear sway bar.. that would probably be better with... I don't find it on rockauto. Where could I buy that ?

With the tires on the ground, push down on the body of the car in a harmonic manner to bounce one side. You want the back of the car to be moving up and down.

When you stop pushing the car should immediately stop moving. if the car continues to move, the shocks need replacing.

Rear swaybars are generally an aftermarket performance item. Summit, jegs, umi, etc. sell them.

fast forward to 1 minute 45 seconds (1:45) to see what is the rear fender and how to check your shocks.

Hi guys !
Thanks for your answers !
I checked the shocks like the guy do in the video and I think my shocks are good, the car stops bouncing very quickly.
I was checking on lower control arms where to bolt a rear sway bar and I found out that I had a leveler on my left rear spring but not on the rear right spring !!
this one :


The previous owner of the car gave me a brand new pair of levelers, so I put these one on both right and left spring and now It seems to be ok ! I have to make more tests but it seems to be a lot better than before !

I would delete that. That is the equivalent of a band-aid for a broken arm. Rear springs are not that expensive, say $60 a pair and very simple to change. Like undo the shocks and jack up the body, the springs will almost fall out.

I see that you are in Tahiti. Are parts for these cars locally available in auto parts stores?

Hi guys !!

I think that the previous owner wanted to raise the back, that's why he put levelers. I'm not sure the springs are bad. But if you think I should change them, I'll do it, it seems pretty simple to do when you describe it !

I don't find GM parts here, I have to order on ebay or rockauto !!

For the sway bar, it's a bit expensive with the shipping, my car is not for performance.. I am going to think about it..
